Poweroff Doesn't Work

guygriffiths · 10-03-2003, 10:02 AM

I have just installed LFS, and automatic power off does not work anymore. It used to in Debian, once I recompiled my kernel to include APM. Now it doesn't. I am using kernel 2.4.22 instead of 2.4.18. I have tried with APM built into the kernel, ACPI built into the kernel, neither built in, but nothing works. Is there something else I need to try?
I am using the command "shutdown -h now", which worked on my old system, but not my current one.
Any help would be most appreciated

see if `init 0` works

Nope. shutdown -h now, init 0 and halt all do the same thing. They stop all processes and display the message "Power down", but none actually do it.
How can I make this work? I thought it was just a case of enabling APM in the kernel, but apparantely not.

maybe your system uses acpi, if so there is a patch for it to make some work better. It's a problem with a lot of laptops.

I don't think it does. My old kernel oly had APM enabled, and that worked fine. Plus it's set to APM in the BIOS. I tried append "apm=on" and append "apm=powerdown" in lilo.conf, which I read somewhere else, but nothing seems to work!
If it was just a case of it not working, that would be fine, but it used to work on Debian, and I'm really not doing anything different!

Have had the same experience moving from 2.4.18-k7 to 2.4.22. I have tried most of the recommendations but nothing works. apm is compiled into both kernels. Also using Debian

i have the same issue with my smp machine (like most other's
smp machine i hear) .. but i just found this out from:
http://sdb.suse.de/sdb/en/html/swieg...power-off.html

basically, pass:
acpismp=force
apm=power-off
to kernel

.. haven't tried yet, but gonna soon ..

That could be it! I heard that you should compile SMP support even if your machine doesn't have it. That's one of the very few differences between my old and my new kernel. I don't have a SMP machine, but I'll give it a go.

any luck on the SMP fix?

I have similar problems on my toshiba satellite. I'm dual booting redhat 9 and mdk 9.1.
Redhat works fine, I can shut down and power off. However,if I log-off or Alt-F2 and run halt the
os shuts down and then just sits there blinking at me until I hit the button.

Mdk 9.1 will shutdown and power off if I run halt, but if I log-off I get a black screen with no prompt
and no combination of keystrokes except ctrl-alt-del works. Weird!
